Well, not really ceiling-less, because that would be a little windy. Emirates, a recent airline company, does offer their unique stars and moodlighting system. This display simulates the time of day at your destination. If it's day, the cabin is bright and sunny. If it's night time, Emirates projects the stars on to the ceiling.
Implications - Luxury air travel continues to push the boundaries of exclusivity and opulence. From personal cabins to private airplane showers, commercial airlines are increasingly including extravagant amenities to appeal to discerning international travelers. By including natural elements into airplane interiors, such as starlight and time-sensitive mood lighting, designers can create a one-of-a-kind travel experience that is a destination in its own right.
